Audi RS5 & RS5 Sportback 2-Piece Brake Guide (B9)

By Slyde Over Team
September 30, 2026

RS5 Sportback owners must match factory front rotor type. 777-XE1558 fits carbon-ceramic front OEM cars; 777-XE1559 fits iron front OEM cars. Product pages cross-link between variants so you do not buy the wrong kit from a Shopping listing.

Iron conversion narrative

GiroDisc markets an RS3 iron conversion front kit at premium pricing. If your RS5 already has iron fronts, 777-XE1559 is the direct 2-piece upgrade with pads included — not a rotor-only pair.

Browse Audi RS5 brake kits, confirm fitment in the vehicle selector, or read 2-piece rotor technology on Ghost Brakes.

Frequently Asked Questions

How do I know if I have iron or carbon-ceramic fronts?

Check your window sticker, dealer service history, or visual rotor hat marking. When in doubt, measure rotor weight/thickness or consult the variant links on each PDP.

Audi Rs5 Brake Kit Shopping Checklist

Before you add a audi rs5 brake kit to cart, confirm rotor diameter, hat height, and pad shape for your exact year and performance package. Optional packages (sport brakes, track packages, tow packages) can change front rotor size even when the model name on the window sticker looks the same. Use our Audi Rs5 shop-by-car page to filter live SKUs, or open the year-specific fitment link from that hub if you already know your trim.

Match rotors and pads as a set whenever possible. Fresh pads on worn or heat-checked rotors transfer uneven friction material and feel like "warp" within a few hundred miles. Ghost Brakes kits ship matched G11H18 rotors (or 2-piece fronts where offered) with carbon ceramic pads so thermal capacity and friction stay balanced axle to axle.

Compare tier choices in our 2-piece vs 1-piece rotor guide and read Ghost Brakes vs Brembo if you are deciding between dealer OEM replacements and a performance-minded upgrade that still bolts to factory calipers.

Install, Bedding, and When to Upgrade Audi Rs5 Brakes

Plan on a standard brake service timeline: clean hub faces, replace hardware where included, torque lugs to spec, and bed pads using the steps in our performance rotor break-in guide. Skipping bedding is the fastest way to get noise, dust, or a long pedal on otherwise good hardware — especially on heavier or AWD variants where the front axle does most of the work.

Upgrade when you feel fade on repeated hard stops, see blueing on factory rotors, or fight constant dust on expensive wheels. Maintenance intervals alone do not tell the whole story for enthusiast driving. When you are ready to order, browse the full brake kit catalog or return to the Audi Rs5 hub for model-filtered kits.

Rotor slot and coating engineering is documented on Ghost Brakes technology pages — Slyde Over handles checkout, tracking, and warranty registration for every complete kit.
